Of the many bug bears with DVR, this is possibly one of the most frustrating, certainly in my top 3. I can’t quite put my finger on it but I think what’s happening is the Program Guide does not load one slot of a show and then the DVR doesn’t know what to do with it. The problem is it breaks Live TV and I can’t even watch the channel. I have seen that Live TV only works with a Program Guide (annoying) so when this breaks things suffer as a consequence. Has anyone confirmed this or have a workaround to watch Live TV without a Program Guide?
